Description: 抛开别的,现在只说细化。
细化的目的是把图像变成单像素宽。
单像素宽的定义如下:
在8邻域内最多不超过3个临接点。
端点处一个,连续点处2个,分叉点处3个
可是如果这样定义,那么这样的图形无法细化了:
图像是一个叉子,因为交点所在的8邻域是有4个临界点的
这样的图像是无法变成单像素宽的
-Set aside other, and now only refinement. The purpose is to refine the image into a single pixel wide. Single pixel width is defined as follows: in the 8 neighborhood of up to more than 3 clinical contact. Endpoint Department one of two consecutive points, bifurcation points 3 However, if such a definition, then this kind of graphics can not be refined: the image is a fork, because the point of intersection where the 8-neighborhood is the critical point 4 of this images can not be turned into a single pixel wide Platform: |

Description: 人耳识别技术是20世纪90年代末开始兴起的一种生物特征识别技术,与其它生物特征识别技术比较具有以下几个特点:(1)与人脸识别方法比较,耳识别方法不受面部表情、化妆品和胡须变化的影响,同时保留了面部识别图象采集方便的优点,与人脸相比,整个人耳的颜色更加一致、图像尺寸更小,数据处理量也更小。(2)与指纹识别方法比较,耳图象的获取是一种被动方式,即通过非接触方式获取耳图像,不存在通过接触传染疾病的机会,因此,其信息获取方式具有容易被人接受的优点。(3)与虹膜识别方法比较,首先,由于人脸和头发的存在,需要在耳识别过程中增加一个耳区域定位步骤,这并不影响耳特征的提取,而眼毛对虹膜的遮挡将直接影响虹膜特征的提取。头发对于耳的遮挡可以容易地避免,而眼毛对于虹膜的遮挡是生理结构决定的,也是难以避免的。其次,就目前的技术而言,虹膜采集需要测试者与采集装置之间的位置在机器发出的语言提示下进行不断地调整,同时要瞪大眼睛,使虹膜尽可能暴露,初试者通常要反复多次调整才能够达到要求,而耳采集方式与脸采集方式基本相同,测试者很容易达到拍摄图象的要求条件。最后,虹膜采集装置的成本要高于耳采集装置。-ear recognition technology of the 20th century, the beginning of the end of the 1990s the rise of a biometric identification technology, and other biometric identification technology compared with the following characteristics : (1) and face recognition methods, Ear Recognition from facial expressions, cosmetics and beards change, while retaining a facial recognition image acquisition convenience advantages, and face, the ears of the whole person more consistent color. Image size is smaller, the amount of data processing are even smaller. (2) and fingerprint identification methods, the ear image acquisition is a passive way, through non-contact ear acquire images, and there is no disease transmitted by the opportunity, therefore, its way to obtain information is easily accepted advantages.
